The best way to envision the relation between ENSO and precipitation over East Africa is to regard the Indian Ocean as a mirror of the Pacific Ocean sea surface temperature anomalies [much like the Western Hemisphere Warm Pool creates such a SST mirror with the Atlantic Ocean too]: during a La Niña episode, waters in the eastern Pacific are relatively cool as strong trade winds blow the tropically Sun - warmed waters far towards the west.

Rather, the observed doubling of the occurrence of 1 - SD drought years has coincided with a doubling of the frequency with which a negative precipitation year produces a 1 - SD drought, with 55 % of negative precipitation years in 1995 — 2014 co-occurring with a — 1.0 SD PMDI anomaly, compared with 27 % in 1896 — 1994 (Fig. 1 A and B).

In addition, the probability of a — 1.5 SD precipitation anomaly increases in spring (P < 0.001) and autumn (P = 0.01) in 2006 — 2080 relative to 1920 — 2005, with spring occurrence increasing by ∼ 75 % and autumn occurrence increasing by ∼ 44 % — which represents a substantial and statistically significant increase in the risk of extremely low - precipitation events at both margins of California's wet season.

During 1995 — 2014, 6 of the 8 moderately dry years produced 1 - SD drought (Fig. 1A), with all 6 occurring in years in which the precipitation anomaly exceeded — 0.5 SD and the temperature anomaly exceeded 0.5 SD (Fig. 1C).

In addition, the number of multiyear periods in which a — 0.5 SD precipitation anomaly co-occurs with a 0.5 SD temperature anomaly more than doubles between the Historical and RCP8.5 experiments (Fig. 4A).

The fact that the occurrence of warm and moderately dry years approaches that of moderately dry years in the last decades of the Historical experiment (Fig. 3 B and C) and that 91 % of negative precipitation years in 1995 — 2014 co-occurred with warm anomalies (Fig. 1B) suggests possible emergence of a regime in which nearly all dry years co-occur with warm conditions.

Similarly, negative precipitation anomalies are much more likely to produce 1 - SD drought if they co-occur with a positive temperature anomaly.

The probability that a negative precipitation anomaly co-occurs with a positive temperature anomaly has increased recently, with warm — dry years occurring more than twice as often in the past two decades (91 %) as in the preceding century (42 %)(Fig. 1B).
